Stress is the body's response to pressure or demands, triggered by situations or events that challenge or threaten a person's sense of control or well- being. It involves physical, mental, and emotional reactions, often including the release of stress hormones that prepare the body for a "fight or flight" response. Stress can be short-term and helpful, such as motivating focus or quick action, but prolonged or excessive stress can lead to negative effects on both physical and mental health. It may cause symptoms like anxiety, irritability, headaches, or trouble sleeping and can increase the risk of health problems if not managed properly.
